All Of July 2009: Tumblr Did 250 Million Pageviews. May 16, 2011: Tumblr Did... 250 Million Pageviews
Two years ago, Tumblr founder David Karp shared some impressive numbers. In July 2009, Tumblr had 50 million visitors, 255 million pageviews, and 650,000 new posts per day.
Context & Ripple Effects
The comparison TechCrunch is drawing comes straight from founder David Karp's own numbers: in July 2009 Tumblr reported 255 million pageviews — a full month of traffic. On May 16, 2011 it recorded roughly 250 million pageviews in a single day, meaning daily volume now runs at roughly thirty times its 2009 pace.
That trajectory explains the confidence behind the $30 million round Tumblr closed in December 2010, when the service had already overtaken WordPress.com on raw pageviews despite hosting fewer bloggers. It also explains the operational strain: an April 2011 outage and reported friction inside the company as it scaled suggest the infrastructure is chasing the curve.
First-order effects
- Advertisers and media buyers looking at Tumblr now see a consumption property whose daily traffic rivals its entire 2009 monthly footprint — a step-change in the audience scale being pitched against traditional blogs.
- David Karp's team faces immediate capacity pressure: after the April outage, sustaining multi-hundred-million-pageview days becomes an engineering problem rather than a marketing claim.
Second-order effects
- WordPress.com's position as the default measure of blogging scale erodes further — the December 2010 pageview comparison flips from close race to different weight class, forcing Automattic to compete on publisher economics or tooling instead of raw traffic.
- Hosting and bandwidth costs scale directly with reblog-driven traffic, pushing Tumblr toward monetization decisions sooner than its headcount or revenue maturity would otherwise demand.
Third-order effects
- If the pattern holds, blog-platform competition shifts from counting hosted bloggers to measuring consumed pages — a structural win for lightweight, network-driven services over per-site publishing tools, and a headache for measurement firms whose categories were built around the latter.
- Sustained hypergrowth at this rate makes outages a recurring feature of the category, raising the odds that reliability — not features — becomes the differentiator investors and publishers price.
The trend: Publishing platforms are being valued on consumed page volume rather than creator counts, and Tumblr's two-year jump from month-scale to day-scale traffic is the sharpest single illustration of that shift.
